View Full Version : [ubuntu] Help! Windows 8 has disappeared!

I just bought an Acer laptop with Windows 8 preinstalled (no windows disk). I reduced the windows partition and tried to install LinuxMint but it seems I can't do that with the current partitioning format, so I turned to Ubuntu. I have had success installing Ubuntu but Grub2 doesn't appear when Iboot- it just goes straight into Ubunto!?

I have tried holding down shift during boot to no avail. I tried control-alt-delete during boot which didn't seem to do anything. If anybody knows what has gone wrong I would appreciate any insights.

The boot-info-script is as follows:

The key to try is the left <Shift> key. Right after the BIOS POST messages, start pressing it repeatedly, not held down. If it still boots directly into Ubuntu without showing a menu... Then follow these instructions: Forcing Grub to Show Menu (http://ubuntuforums.org/showpost.php?p=11469860&postcount=800) But it boots into Ubuntu right???

With a dual-boot, it should have presented a menu if it found another OS present. In your case Windows 8. I see your GPT partition... But then:


### BEGIN /etc/grub.d/30_uefi-firmware
###### END /etc/grub.d/30_uefi-firmware ###
...
GUID Partition Table detected

Since it didn't find that... It did't find your install of Win8. It wasn't running in uefi mode when it installed Ubuntu, so when it installed the boot loader, it again wasn't running in efi mode and didn't see Win8. Most new systems running Win8 are running on efi or secure boot... That's what I see going on.

I think "oldfred" summed it up best here:

Although his comment on: "Windows is not designed to multi-boot" is a little slighted. Windows Boot Manager can be made to multi-boot other OS'es, but it really favors other Windows OS'es and it is not easy to do for normal non-technical users.

Advice? He recommends Yann's "Boot Repair ISO." Another would be the Secure Boot ISO.

Is this an UltraBook?
It looks like the 20GB drive is a small SSD for caching Windows. That uses Intel SRT which somehow uses RAID and grub does not install to RAID from the desktop and with that type of RAID you do not want it installing inside the RAID anyway.

Ubuntu on hard drive, re-enable SRT post #19 details

Disable the RAID, it was using the Intel rapid management thingy and telling it to disable the acceleration or the use of the SSD. If you have a different system, just disable the RAID system then install Ubuntu. Once installed you can then re-enable it.
sudo dmraid -E -r /dev/sda
sudo dmraid -E -r /dev/sdb

You will need to use the dmraid command prior to running the Ubuntu Installer so that it will be able to see the partitions on the drive because otherwise with the raid metadata in place it will see the drive as part of a raid set and ignore its partitions.

Hi guys,

First of all thanks to you both for for replying. Unfortunately I didn't see either of your replies before wasting a lot of time on this problem and then finally solving it.

In the (F12) boot menu Windows Boot Manager wasn't coming up,so in the (F2) menu I restored the boot to factory settings, disabling secure boot. This allowed me to boot to windows only, unless I changed the boot order (F2) to put the HDD boot ahead of Windows Boot Manager (which had now returned) allowing me to boot to Ubuntu only. I thithis was working because I set the Ubuntu boot sector to loadin the root drive (didn't specify a partition). Still no option at startup.

Then I burnt the ISO of "Boot Repair Disc" onto a DVD to run, but couldn't work out how to make the disc run at boot, even when I bumped the DVD reader to the top of the boot sequence! Finally I found a page that gave me simple instructions to upload and run Boot Repair disc from the Ubuntu console:
http://askubuntu.com/questions/278192/cant-boot-windows-8-after-installing-ubuntu-12-10
I ran recommended repair and done!

Took a while longer to fix my partition sizes and add more useful mount points to my existing partitions, but that was another story! Enjoying the steep learning curve on Ubuntu

Cheers
